The influence of indium on the properties of Pt–Re/Al2O3 catalysts used in naphtha reforming is studied. The addition of indium to the Pt–Re/Al2O3 catalyst produces a big decrease of acidity. It also produces an inhibition of the metal function, i.e., dehydrogenation and hydrogenolysis activity. The reaction of n-C5 isomerization shows that indium addition decreases the total activity of the Pt–Re catalyst but increases the selectivity to the i-C5 shows that indium addition decreases the total activity of the Pt–Re catalyst but increases the selectivity to the i-C5 produces a big decrease of acidity. It also produces an inhibition of the metal function, i.e., dehydrogenation and hydrogenolysis activity.

The selectivity to low cost light gases (C1–C3) is particularly decreased. The reaction of n-C7 reforming showed that addition of indium increases the stability of the catalyst and the selectivity to aromatics, and decreases the production of light gases. showed that addition of indium increases the stability of the catalyst and the selectivity to aromatics, and decreases the production of light gases. particularly decreased.
